Metals magnate is experiencing a rebirth of sorts. In 1990s was one of the best-known Russian businessmen, co-owner of aluminum plants and the bank Rossiyskiy Kredit. In 2000 sold all his holdings in Russia and was quiet for four years. Then in 2004 made a triumphant comeback as co-owner, with fellow billionaire Alisher Usmanov, of Metalloinvest Holding, one of Russia's largest ore mining and processing firms. Has postponed a London initial public offering of Metalloinvest but plans to build, with partial government financing, a large affordable-housing development outside Moscow. Daughter Anna Anisimova, a high-profile member of the growing diaspora of wealthy Russians in the U.S., plans to launch her own perfume line.
